I started to learn Selenium. After creating the project I tried to add some jar files.

As you see all required jars were added. But

...sources.jar

looks like Empty Project. Why this is happening?

CodePudding user response：

Probably this happening because ...source.jar file has a multiple files.

1. Click Libraries from Project Settings

2. and add this .jar file here first.

3. When you added turn back to Modules

After these steps "Empty library" error is gone.
